Why my Nikon flashes automatically switches from TTL to A Mode?

Question:I cannot remote power control my Nikon SB700, SB900 and SB910: Flash automatically switches from TTL to A Mode and would not let me switch back.

Answer:What you need to do switch off your V6 Receiver unit(s) before switching on your Nikon flash on the V6. First switch the flash on, set it to TTL mode. Then switch on the V6 by selecting RX Mode and select the correct flash profile.

Note: Flash must be in TTL mode, so when it is in “A” or “M”, the V6 is cannot remote power control the unit.

To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "v.103".

Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.A.001 and OLY.A.001. Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.

Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).
